'Ihe Schedule referred to in these Letters Patent and inakng part of thes ane.

To all whom it may con-cern:

Be it known that LJ. BURcHARDv CHAPMAN, of Morrison, in the county oflVhiteside, and State of Il- Gorn-Planters; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part ofv thisspecification, in which- Figure 1 is a plan or top view of my improvedmachine.

My invention relates 'ancora-planters; and

My improve-ments consist in the construction, coinhination, andarrangement of its several parts, as hereinafter more fully described.

To enablethose skilled in the art to make and use my invention, I willproceed to describe its construction and operation. A j A A'A', in thedrawings, represent the frame of the machine, 'which may be constructedas shown, or in any manner which may be found to. be the best adapted tothe purpose for which it is to be used. To the iiout end of it, the poleis to be' attached, which is here provided with a swivel-wheel, A2, ofsufficientdiameter to assist in supporting the machine.

A1 is a cross-beam of the frame, secured to it just in front of thecovering-wheels when they are in their most forward position, and towhich the seed-boxes are to be secured. One end of this cross-beamextends some distance beyond vthe outer covering-wheel, and to thisv endthe shoe G is to be secured.

A seat, a, for the operator, may be mounted on the frame, as shown, orin any other convenientfmanner.

B represents the axle, the journals of which rest in the hubs of thecovering-wheels. To the upper side of its square portion, a shaft, B',having its bearings in the rear end of the frame, is firmly secured. Itwill h e seen, by reference to iig. 4 of the drawings, that as the axleis turned on i-ts centre in the direction indicated by the dotted ,redline, the shaft B will be` lowered, carrying with it the frame A, untilit is in the position indicated by the red outlines, when the furthermovement of the axle is arrested by abutting against projecting lips ofthe frame. This movement isaei complished by means of the lever b, whichis secured linois, have invented new and useful, Improvements in to therear side of the axle, and extends upward a suf.- iieient distance, soas to be within easy reach of the operator. By the above-describedarrangement, the operatoris enabled to lower the seed-boxes, which, asstated, are firmly secured to the frame, sufiiciently that the couitersfastened to their bottoms will enter the earth, to make a furrowfor theseed to 'fall into, and

raise them above the surface of the ground, as circum stances mayrequire.

C C C G represent the covering-wheels, which, at the same time, are thecarrying-wheels of the machine. They revolve on the journals of the axleB, and are tobe made of a' suitable diameter. The faces of thc rims ofeach set are bcvelled, so. as to converge toward each other, whichconstruction will have the effect of pushing the earth thrown up by theconlters back into the furrow, and covering the seed as the machine ismoved along.

- D D represent the seed-boxes, which are secured to the cross-beam Alof the frame, one between cach set of the covering-wheels. The bottom ofeach box is provided with'a conlter, D', instead of the ordinary shoe,for making a furrow, intowhichvthe seed is to be dropped, said'hoxesextending downward such a'distance, that when in their most elevatedposition, the coulters are just above the ground." The interiorarrangement ofthe seed-boxes is clearly shown in g. 3, each beingdivided into two compartments, the upper one of which is for thereception of the seed, which drops, through a passage, on the seed-slideg and in the other one, the lever operating the seed-slideand thedropper are placed. The low with suitable aperture, in rear of thecoulter, through which the-seed may fall into the furrow. E E representthe seed-slides, which work in slots in the sides 'of the seed-boxes,underthe passage of the same. made in it, of the required size, which,when brought under the passage of the seed-box, will be filled withseed, which drops, as the slide is drawn outward, on the dropper E..This dropper is pivotedl in the lower portion of the seed-box,partitioning, but workin g freely in the same, and is simply a lever,one arm of which extends upward througha slot, e', in the seed-slide,while the other extends downward to near the bottom -of the box, beingpivotcd-s'o, relatively to the .seedslide, that as the cup e in thelatter is being filled with seed, its lower arm is in the positionindicated by the black outlines in iig. 3, permitting any seed which maypreviously have been dropped on it to fall throughthe aperture in thebottomof the box, and into the vfurrow; and assuming the position'indicated by the vred er bottom'is provided n Each has, in the properplace, a hole, e,

outlines when'the slide is drawn out, so that the seed lmay fall on it,and be held in the box until it is again loperated upon.

F represents a rock-shaft, having its bearings in the sides of theseed-boxes -some distance above the seedslides, so as to gi e sucientleverage to the levers F2,

extending from it downward through the-slots ef in the slides, and bywhich the latter as well as the droppers are operated. One end ofthisshaft extends such distance beyond the seed-box that the lever F1,which is firmly secured to the end of it, andextends downward o at arightangle to it, will be in line lwith the shoe G, soon to bedescribed. The extreme end of this lever F is provided with a notch, f.l

F3 represents a lever or arm, one end of which is firmly secured totheshaft F, at any convenient place, and carrying, at its other end, aweight Suiiciently heavy to return the shaft to its normal positionafter it has been opi-rated upon. G represents a shoe, which is firmlysecured to the end of -the cross-beam A by means of a 'connectingtimber,being high enough above the gronudin its .Y lowest position .to go clearof any unevenness iu the surface of the same. Its outer face has anupwardprojecting ange, for the purpose oi' preventing the rope or chain,which is to slide in the groove' g, on its upper surface, from slippingoff. From the timber which connects this shoe lwith the cross-beam A,extends an arm, in a horizontal direction,'aud forward of the shoe, towhich a stud is secured, on which a roller or pulley, G', of suitablediameter, revolves horizontally, for the purpose of guiding the chain,when thisisnsed, or onwhich the rope may be wound, when this ispreferred asa means of operating the lever F1. 'lhe extreme end of thislever cornes down to just above the upper surface ofthe shoe, the4latter being placed. at such an angle that the distance between them isnot increased as the lever is made to oscillate to the rear -'until itis carried -beyoud the shoe.-

H represents a chain, which is to be of suicient length to reach acrossthe field in which corn or other seed is to be planted, and have some tospare, its links l being about equal in length to the usual distancebetween-each hill of corn. the eld, passing through the groove g' in theshoe, and corresponding notch f in theend of lever F1, and over thepulley G. If the machine be now drawn along' the chain, the eyes of itslinks will cause the lever F1 to oscillate to the rear, and drop theseed at regular intervals, the lever being returned to its normal posi-'tion by the counterweight the moment the eyes ofthe links escape fromit. If preferred, a rope, provided, at"

regular intervals, with round balls, to serve the purpose of the eyes ofthe chain, may be used, saidvrope to be stretched across the -iield thesame as the chain,

or it may be wound on the pulley, one end of'it being secured at thepoint of starting, and paid out asthe machine moves along. By employinga chain or rope, as above described, the seed can be planted more regvend of the carried on the machine, paid out, as the latter is moved Itis to be stretched across employ in securing the chain or rope attheends of4 the rows, and by means of which the operator-.lis ena.- bledto shift the chain or rope when he arrives at one end thereof, so as toplant both ways. `This is done in the following manner: i

' The chainor rope, having been stretched across the field, is passedthrough the notch in the stake I, which has previously been driven intothe ground at the point of starting, in rear of the shoe of the machine,and is then carried along, at a right angle thereto, some distance, whenit is again secured to the ground by a common stake. The end of a lineis now tied, or secured in any other convenient manuer, to the extremepurchase on stake I, and, such line being along the chain, until-theother end has `been reached. In order to shift the` chain now, the stakeI, at the further end, is pulled up by means of the line, when the chaincan be stretched across the field from the point where it is secured bythe common` stake at the other end, being such distance from the. rowsjust planted, that'iu returning, two more rows are planted the properdistance from the former. Before returning ou theuew line, the chain atthis Vend of the rows is arranged in the manner above described, sothat-on reaching the other end, it can be again shifted. lhus theoperation is continued. Y,

Having thus described my invention,

What I claim, andI desire to secure by Letters Patent, is- Y I. vThecombination of thev axle B with the shaft B', being arranged, withreference to the frame and seedboxes, so as to operate substantially asshown and described'.

2. The combiuatiou, iu a seed-box, of the seed-slide E with thedropperE, substantiallyas and for the purpose set forth.

3. The combination of the rock-shaft F, having the levers F and F2, withthe seed-slides E land drppers E', substantially as shown and described.

4. The combination of the rook-shaft F and lever F, having acounterweight, substantially asV and for the purpose set forth.

5. lhe combination of the shoe G with the lever F1, of the rock-shaft F,and the chain H, or its equiv-A aient, arranged to operate substantiallyas shown and described.

6. The stake I, constructed substantially as shown and described.

In testimony whereof, I have vsigned my name to f this specification, iuthe presence of two subscribing witnesses.
